It will be like any other Automatic that did not come from the factory with the Temp Gauge. I cut the Transmission Oil line to the cooler and inserted a Tee Fitting to hold the Temperature Sensor, I sized the Tee so the Sensor end was in the middle of the transmission oil line. Being steel lines I did not have to ground the sensor. I also removed the transmission Oil Pan and Silver Brazed some Flat Stock to the Side and drilled and tapped a hole in the Pan/Flat Stock for another sensor (1/8" National Pipe Thread). I selected between the sensors with a switch so I could read any of 6 different sensors on my Tow Vehicle, 1:Rear End, 2: Transfer Case, 3: Transmission Oil Pan, 4: Transmission Oil to the Cooler, 5: Engine Oil to Oil Cooler and finally 6: Jacket Water Temp in the engine.

It was over kill, but I enjoyed checking the various temperatures as I pulled a steep grade. This did allow only one gauge so I could fit it in a small crowded dash in a 75 Scout II.

I agree with the above. But make sure you are on the outlet to the cooler. That is the key. The outlet!
